- Update to 0.9.2:
* OpenSSL tls module verifies certificate by default. Set flag XMPP_CONN_FLAG_TRUST_TLS to ignore result of the verification
* Certificate hostname verification is forced for openssl-1.0.2 and newer
* OpenSSL tls module disables insecure SSLv2 SSLv3 and TLSv1
* Support of handlers with the same callback function, but different userdata
* System handlers are deleted on xmpp_conn_t reconnection. Old system handlers could cause problems
* Default timeout for xmpp_run() is increased from 1 millisecond to 1 second in order to reduce CPU consumption
* Reduced memory usage in expat module
* New functions: xmpp_ctx_set_timeout(), xmpp_sha1_digest()
